ABSTRACT

AIM To investigate the clinical effects of Huoxue Huayu Decoction (Angelicae sinensis Radix,Saposhnikoviae Radix,Schizonepetae Herba,etc.) combined with musculus pterygoideus lateralis closure in managing patients with temporomandibular joint dysfunction syndrome (TMJ) due to wind-cold stasis.METHODS From January 2015 to December 2015,68 cases of patients with TMJ due to wind-cold stasis identified and recruited by the department of stomatology of Hebei Provincial Hospital of Traditional Chinese Medicine were randomly assigned to treatment group and control group,each with 34 cases and given the musculus pterygoideus lateralis closure.But the treatment group was administered with an extra two-week adjuvant therapy of Huoxue Huayu Decoction,and generally one week such medication was taken as a therapeutic course.RESULTS After the intervention,the treatment group presented an overall better performance than the control group in terms of the open limit,NRS score,and the differences were statistically significant (P ＜ 0.05);and the values of CMI,PI,DI (P ＜0.05),in contrast to the not significantly varied values between the groups before the intervention (P ＞ 0.05).The treatment group also displayed its advantage if evaluated by TCM criteria,extent of the mandibular movementabnormalities,facial pain,temporomandibular joint sound or noise,irritability,sleeping difficulty,dark purple lips,tongue scores and wind-cold stasis scores (P ＜ 0.05).And generally a remarkably higher total effective rate was observed in the treatment group,and its difference to the control group was statistically significant (P ＜0.05).CONCLUSION Huoxue Huayu Decoction combined with conventional western medicinal approach in the management of TMJ due to wind-cold stasis can achieve a better therapeutic efficacy.
